microcomputer controlled electronic ring stiffness testing

machine

Equipment overview:

LD69series microcomputer control electronic loop stiffness testing machine is a new type of material testing machine which is electronic technology and mechanical transmission. It has a wide range of loading speed and measuring range. It has high accuracy and sensitivity. It can also be controlled by constant velocity and constant velocity.

Main function:

The series models are mainly suitable for the test of the stiffness of the pipe ring, and meet a series of relevant test standards. Can be equipped with electronic universal testing machine fixture, electronic universal testing machine related functions.

Main features:

1: the use of high-speed DSP platform, its high integration, powerful control, data processing ability, high reliability, is the use of other processors can not match the test machine.

2: the full digital, three closed-loop (force, deformation, displacement) control system based on neuron adaptive PID algorithm, the realization of force, deformation, displacement of the whole digital three closed-loop control, the control loop can be automatically switched, and the switch between the different ways to achieve smooth transition.

3: can carry out the test force, deformation, displacement and other rate control and maintain.

4: closed loop control parameters on-line identification.

5: high precision 24Bit data acquisition system, high resolution, can be extended to 8 AD acquisition.

USB1.1 6: communication, communication rate is 12Mb/s, the use of full speed mode, bulk transfer mode.

7: system board uses 4 layers of PCB unique anti interference routing method, strong anti-interference ability.

8: in addition to the power interface, the other interfaces are the standard USB type interface, plug and play interface such interface can be used to achieve hot swap, that is, plug and play function. Interface features can be set up by software online. The interface neat layout reasonable, convenient plug.

9: the whole control system has a very high cost, high reliability.

10: the whole test process is controlled by microcomputer, and the load value, displacement, deformation, test speed and test curve are displayed in real time.

11: uses microcomputer for data processing and analysis. The test results can be saved automatically. After the end of the experiment, the test curve can be re - up.

12: full Chinese Windows platform under the test software, with a strong data and graphics processing functions, can print out the complete test report and test curve.

13: have the perfect protection, overload protection, emergency stop and other safety protection function.
